The product is meant to be simple, to be adaptable. This iteration uses Adafruit Huzzah with ESP, but keep in mind that in the next iteration we intend to use a LoRa version. Here is how you can build this project yourself

2

Step 2

Get the components we recommended or some alternatives for them (be advised that you might need to tweak the code for the second option)

Step 3

Assemble the components in the following way for the code to work:

Connect the mercury tilt switch or the moisture sensor to the ADC pin of the Feather Huzzah

The device will try to send the information to a nearby device programmed to work also in a mesh network. In order to test it, you should build at least two of them. Shake one of them for earthquake simulation and the other will receive a warning. The LED of the receiver will start blinking. In order to use the device, take in account to eliminate the false positives.
